IOW, the event delegate is essentially called synchronously. You can fake async usage in the method, and use the async void method declaration, which gives you the ability to use await code inside of your event handler: csharp public async void HandleAnEvent() { await Task.Delay(100); ....
WhenGetUrlContentLengthAsynchas the string result, the method can calculate the length of the string. Then the work ofGetUrlContentLengthAsyncis also complete, and the waiting event handler can resume. In the full example at the end of the topic, you can confirm that the event handler...

DoStuffCompleted; } public delegate void DoStuffEventHandler(object sender, DoStuffEventArgs e); public class DoStuffEventArgs : AsyncCompletedEventArgs { public D...
如上图,首先定义一个专属的异常处理handler,然后将handler接入AsyncConfig。 这样,异步处理的异常就会进到Handler方法中,可以根据method、参数等信息进行专门的处理,也可以接入事件驱动等进行分发处理。 有返回值的@Async可以直接在方法中进行throw处理,最终异常会进入get阻塞catch块中,注意把异常信息往上抛即可,也可以在...
